This book is based on Swift 3 Developer preview version and aims at simplifying the functional programming (FP) paradigms making it easily usable, by showing you how to solve many of your day-to-day development problems.
Whether you are new to functional programming and Swift or experienced, this book will strengthen the skills you need to design and develop high-quality, scalable, and efficient applications.
The book starts with functional programming concepts, the basics of Swift 3, and essential concepts such as functions, closures, optionals, enumerations, immutability, and generics in detail with coding examples.
Furthermore, this book introduces more advanced topics such as function composition, monads, functors, applicative functors, memoization, lenses, algebraic data types, functional data structures, functional reactive programming (FRP), protocol-oriented programming (POP) and mixing object-oriented programming (OOP) with functional programming (FP) paradigms.
Finally, this book provides a working code example of a front-end application developed with these techniques and its corresponding back-end application developed with Swift.
